Why is the covenant relationship with God important for believers?

The covenant relationship is foundational for believers because it signifies an intimate connection with God through Jesus Christ. In this relationship, God promises to provide for, protect, and guide His people. As seen in 2 Samuel 5, David made a covenant with Israel as their king, which parallels how Christ entered into a covenant with us. Through His sacrifice, we are granted access to grace and the assurance of His steadfast love, as well as the promise that He will never leave or forsake us in our journeys.
